Apo substation : TCN restores normal bulk power transmission

Transmission Company of Nigeria (TCN), says it has restored normal bulk transmission of electricity to its Apo transmission substation after a fire outbreak on one of its 45MVA 132/33kV power transformers on Sunday.

She, however, said the Apo transmission substation had N-I redundancy and as such, power supply to all the areas that take supply from the substation through AEDC would not be affected by the incident.

“This is because the maximum load taken by AEDC from the burnt 45MVA transformer was 26MW, meanwhile maximum load AEDC takes from the old 100MVA in the substation is 56.5MW.

“But maximum load from the second 100MVA power transformer installed last year is 30.8MW, both however, can take at full capacity, a total of 160MW as against the 86.5MW.’’

She said TCN was presently transmitting normal supply through the 2x100MVA 330/132kV and the second 45MVA 132/33kv power transformers in the substation.

According to her, the company had equally loaded the 26MW from the burnt transformer into the 100MVA MBH transformer at the substation and is adequately supplying AEDC without load reduction.
